Background

The foam molding equipment is mainly used for compression molding of foam plastic materials, and a heating and plasticizing mode is usually used. The existing foam plastic molding equipment comprises a rack, a feeding mechanism and a molding mechanism, wherein the feeding mechanism and the molding mechanism are arranged on the rack, and the molding mechanism comprises a fixed template, a movable template and a hydraulic cylinder which is used for driving the movable template to compress or keep away from the fixed template. After the movable template and the fixed template are assembled, a mold cavity is formed between the movable template and the fixed template, foam plastic is filled into the mold cavity through the feeding mechanism, and then high-temperature steam is used for expanding and molding raw material particles in the mold cavity. Demoulding and blanking are needed after forming. Because the product is prepared in the environment of high-temperature steam, the temperature of the product is very high, manual blanking is inconvenient, and because the product is expanded due to high temperature, the product is tightly contacted with a mould, and the demoulding operation of the product is not easy. Therefore, the product is generally cooled before the product is demolded and blanked, but the temperature after cooling is generally kept at 70 degrees celsius or higher because the mold needs to be preheated for a long time in the next production of the product after the cooling temperature is too low.

The traditional cooling method is to introduce cooling water into the mold cavity, and the operation often causes too long cooling time and affects the production efficiency. And cooling through the cooling water, although improved cooling efficiency, can remain a large amount of moisture on the product, lead to the moisture content of product too high, need follow-up dehydration work, increased production processes, prolonged production cycle, reduced production efficiency, also have at present to equip the method that the vacuum pump cools on foam molding equipment, the vacuum pump starts at every turn-on when cooling, takes away gas and water in the die cavity, but this kind of method has following shortcoming in the in-service use process: 1. the vacuum pump is easy to absorb water mist into the vacuum pump in the negative pressure air extraction process, the service life of the vacuum pump is shortened, and the vacuum pump can generate extremely large noise when exhausting air; 2. the gas pumped out by the vacuum pump in the foam forming equipment is high-temperature mixed gas, the high-temperature mixed gas also contains harmful substances such as dust, foaming agent and the like, the direct discharge of the gas can influence the workshop environment and the health of workers, the gas can be discharged after being cooled and filtered, but the conventional cooling system cannot efficiently and stably cool and filter; 3. the mode of introducing cooling water into the die cavity, the cooling water can not be recycled and does not accord with the concept of environmental protection recycling.
